I just Bought a 97 ranger with a/c The heater blows hot all the time even when you turn the temp down all the way. Any Thoughts?:uhoh:

You've got to push in the button on the lower left in (above ash tray) to turn the air on, at least my 94 is in that location. and an A/C light will come on. look under the hood to see if the A/C clutch is turning when the A/C is turned on It won't cool if its not turning.
